The soil physicochemical parameter in Ohaji in Imo State, Nigeria was investigated using Ibeocha, Ekeugba, Awara, Mbirichi and Location as a case study. The result obtained from the soil analysis using standard methods shows that the concentrations of the heavy metals, Pb and Fe were highest in the soil from Ibeocha (0.045 ppm) and Mbirichi (0.126 ppm) which show high rate of industrial activity and oil spill in those areas. There was no remarkable change in pH, but temperature followed the pattern of heavy metal concentration with acidic (lowest) values at the centre. The cation exchange capacity of the soil sample from location (14.066 ppm) shows that this soil sample has a lower contamination to compare to other soil samples from other location. Containment of the effects should be encouraged as soil from these sampling locations is contaminated due to oil spill.

“…This strain has also proved to be an effective partner with both a meta-cleaving phenol degrader strain CP4 and an ortho-cleaving phenol degrader strain SPC-2 for simultaneous degradation of phenol-3-CBA mixtures (Babu et al, 1995a;Jayachandran and Kunhi, 2009). This strain also was shown to bioremediate effectively soils contaminated with 3-chloro and 4-chlorobenzoates, thus eliminating their toxicity and helping the germination of tomato seeds (Ajith-Kumar et al, 1998). All these positive attributes and the results of this study indicate a clear possibility of deploying immobilized cells of these strains for simultaneous degradation of heterogeneous mixtures of phenol/cresol isomers, 3-CBA/4-CBA and other aromatics.…”

Simultaneous degradation of halogenated and non-halogenated aromatic compounds that are catabolised through different cleavage pathways is generally difficult due to biochemical incompatibility. However, free cells of a mixed culture of Pseudomonas sp. CP4 that degrades phenol through meta-pathway and Pseudomonas aeruginosa strain 3mT that degrades 3-chlorobenzoate through ortho-pathway was shown, earlier, to degrade mixtures of phenol/cresols and 3-chlorobenzoate in shake flasks. In the present study the degrading efficiency of these strains when immobilized (separately) in Ca-alginate gel beads was tested using a fluidized bed reactor. Complete mineralization of up to 5 mM equimolar mixture of phenol and 3-chlorobenzoate was observed when the beads were used at 1:1 ratio. From a 10 mM equimolar mixture although phenol was completely mineralized 3-chlorobenzoate degradation was not complete as evidenced by accumulation of some intermediary metabolites and the release of only 86% of inorganic chloride (Cl¯). Degradation rates of both the compounds by the immobilized cells, in general, were far better than that by the free cells. With further studies to select suitable gel matrices and optimization of bioreactor conditions these strains can be effectively deployed for treatment of heterogeneous aromatic wastes.
